Abstract: @ The invention relates to a method and apparatus for refurbishing moderator/coolant displacer rods which were flooded with moderator/coolant liquid in a nuclear reactor during a previous fuel cycle. 
     An air entrance path (96,86) provides fluid flow communication with an upper interior portion (92) of each displacer rod (50), and a separate liquid exit path (88, 98) is in fluid flow communication with a lower interior portion (94) of the displacer rod. By introducing air under pressure through the air entrance path, all the liquid above the level of the inlet (108) to the liquid exit path is forced through the latter and out of the displacer rod.

Abstract: An integrated circuit chip is mounted to an etched circuit board using a flexible, sheet-form interconnect member that comprises a dielectric mate­rial and runs of electrically conductive material supported by the dielectric material in mutually electrically insulated relationship, each run ex­tending between a contact pad is exposed at a first main face of the interconnect member and a termina­tion point that is exposed at a second main face of the interconnect member. The contact pads of the interconnect member correspond in their layout to that of the contact pads of the circuit board, and the termination points correspond in their layout to that of the contact pads of the integrated circuit chip. The interconnect face of the chip and the second main face of the interconnect member are placed in mutually confronting relationship, and the chip is attached to the second main face of the interconnect member by way of its interconnect face, whereby electrically conductive contact is established between the contact pads of the chip and the corresponding termination points of the interconnect member. The chip is attached by way of its back face to a thermally conductive plate that has, at one main face, pressure pads that at least partially surround a chip receiving area of the plate. The first main face of the interconnect member and the main face of the circuit board are placed in mutually confronting relationship, with the contact pads of the interconnect member in registration with the corresponding contact pads of the circuit board. The plate and the circuit board are clamped together, whereby the pressure pads supply contact force to maintain the contact pads   of the interconnect member in electrically conduc­tive pressure contact with the corresponding con­tact pads of the circuit board.

Abstract: A magnetic recording medium is formed by depositing a layer of a cobalt-platinum magnetic alloy (which may also contain chromium) on a non-magnetic underlayer consisting of tungsten, molybdenum, niobium or vanadium. The magnetic alloy has a higher coercivity than when deposited on a chromium underlayer. The coercivity of the magnetic alloy becomes even higher when the substrate is maintained within such a temperature range during deposition of the magnetic alloy that an intermetallic compound of cobalt and the metal of the underlayer is formed at the interface between the magnetic alloy layer and the underlayer.

Abstract: The process for cultivating animal cells to multiply them and/or obtain wanted parts from the cells entails the cells being located in the extracapillary space in an aqueous culture medium in a capillary membrane module, and the supply of nutrients and the removal of metabolites being effected through the interior of the capillary membranes. A carrier material for the cells is located in the extracapillary space, and the cells preferentially adhere thereto. This keeps the membrane surfaces free, and thus a constant optimal supply to and removal of waste products from the cells is ensured. In a preferred embodiment, the capillary membranes are the weft and the carrier material for the cells is the warp of a woven mat which is, for example, introduced in rolled-up form into a module housing.

Abstract: A cyclical wire stitching machine head (10) includes a reciprocating staple-forming and driving apparatus (15) which is coupled to a wire gripping and feeding mechanism (20) which reciprocates with it. During each cycle of the machine the supply wire is gripped and a predetermined length thereof is fed through a cutter (32,33) to a holder (45) and severed while, simultaneously, the length severed in the preceding cycle is formed into a staple and driven through the work against a clincher. On the retraction stroke, the holder is rotated to bring the severed length of wire into position for forming and driving during the next drive stroke. 
     A guide tube (85) positively guides and supports the unstraightened wire from a supply coil along a feed path from the input end of the head to the gripping and feeding mechanism. Guide means (90) are also provided for guiding the wire from the cutter to the holder while accommodating rotation of the severed length of wire with the holder.

Abstract: The invention relates to a method of making a blow-moulded article using a split blow mould. The preform is introduced as a parison in a thermoplastic material state into the opened blow mould halves and, once they have been closed, brought to bear against the inner contours of the blow mould by a defined blowing pressure. After cooling, the blow-moulded article is removed from the opened blow mould. Before inflating, an insert part, located on a displaceable holding device, is introduced into the preform with the blow mould open and is bonded to part of the inner wall of the preform during closing of the blow mould. During closing of the blow mould halves, a pressing pressure is exerted on the wall areas of the preform adjacent to an insert part designed as a reinforcing element. This pressing pressure has the effect of reducing the wall cross-section of the preform in the area of the insert part. If not before, when the pressing pressure from outside commences, the inside of the preform is subjected to the blowing pressure from the inside.
